Connector Assembly Jig for Heat Sink Protection and Leg Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jigs for assembling connector assemblies with heat sinks and guide shielding cages often damage the heat sink due to excessive pressing force and cause misalignment of inserting legs during assembly, especially when the heat sink has thin dissipating fins or wider widths.
Innovation Solution
A jig comprising a pressing cover, movable plates, and supporting springs that grip the guide shielding cage's side walls, allowing the movable plates to move inward and press on the cage's protrusions, avoiding direct pressure on the heat sink and ensuring correct alignment of inserting legs with the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pressing plate is used to press the heat sink downward to assemble the connector, then the assembling operation can be performed, but the dissipating fins of the heat sink may be deformed or damaged
Solution Approach 1:
The pressing portions act as intermediaries between the pressing cover and the guide shielding cage. Instead of pressing the heat sink directly, the pressing portions press the pressed protrusions on the side walls of the guide shielding cage, which then transmit the force to the inserting legs. This intermediary mechanism protects the heat sink from direct pressing force while still achieving the assembly function.
2Productivity
If a pressing plate is positioned on the top surface of the heat sink to apply pressing force, then the connector can be pressed into the circuit board, but the inserting leg may offset relative to the through hole causing distortion deformation
Solution Approach 1:
The pressing function is segmented into multiple pressing portions distributed on different movable plates. Each pressing portion independently presses a pressed protrusion on the side wall of the guide shielding cage, providing localized and balanced pressing force. This segmentation ensures that the inserting legs are pressed uniformly without offsetting or distorting, while still achieving the assembly function.
3Productivity
If a solid metal pressing plate is used to press multiple terminals simultaneously, then the assembly process is efficient, but the pressing force may be off-balance causing inserting legs to misalign
Solution Approach 1:
The movable plates are designed to be movable relative to the pressing cover, allowing them to adjust their positions dynamically during the pressing process. The supporting springs enable the movable plates to move inwardly toward each other when the pressing cover is pressed downwardly, providing adaptive pressing force that maintains balance and alignment while achieving efficient assembly.

AI summary
A jig for assembling a connector assembly is proposed. The connector assembly includes a guide shielding cage and a heat sink which has been assembled on the guide shielding cage, the guide shielding cage includes two side walls which each have a pressed protrusion. The jig includes a pressing cover, two movable plates and a supporting spring. Each movable plate has a connecting portion disposed at an upper portion thereof, a pushed portion disposed below the connecting portion, and an acting construction w disposed below the pushed portion, the pressing cover is assembled with the connecting portions of the two movable plates in a manner that the pressing cover is capable of moving up and down relative to the two movable plates, the two movable plates are arranged laterally and are capable of moving between an unloading state where the two movable plates are away from each other and a loading state where the two movable plates are close to each other, the acting construction has a gripping portion which is inward and a pressing portion which is downward. The supporting spring is provided between the two movable plates. The pressing cover which is pressed downwardly is capable of pushing the pushed portions, so as to make the two movable plates move inwardly toward each other from the unloading state to the loading state, the gripping portions of the two movable plates inwardly grip the two side walls of the guide shielding cage respectively, the pressing portions of the two movable plates downwardly press on the pressed protrusions of the two side walls of the guide shielding cage respectively.
